  • Publication number: 20230219777
    Abstract: A conveying belt has a cylindrical base layer, and a surface layer that is formed on the outer peripheral surface of the base layer. The base layer contains polyimide or polyamide-imide, and has an elastic modulus from 3-7 GPa, inclusive. The surface layer is configured as a cured object from a resin composition that contains a fluororesin having a hydroxy group, an isocyanate curing agent, and a silicone copolymer. The silicone copolymer is a copolymer containing a silicone unit and another kind of unit not having a siloxane skeleton, has a hydroxy group, and contains siloxane units in a proportion of at least 95 mol% and less than 100 mol%, or from 40-70 mol%, inclusive. The silicone copolymer content in the resin composition is 1-5 parts by mass, inclusive, relative to a total 100 parts by mass of the fluororesin and the isocyanate curing agent.

  • Publication number: 20210364954
    Abstract: A fixing member 10 for an electrophotographic device includes a base layer 12, a metal layer 14 formed on the based layer 12, and a protective layer 16 formed on the metal layer 14. The metal layer 14 is configured to form a predetermined pattern. The base layer 12 has a surface 12a which is covered with the metal layer 14 and a surface 12b which is not covered with the metal layer 14. The protective layer 16 continuously covers the surface 12b of the base layer 12 not covered with the metal layer 14 and a surface of the metal layer 14, and is bonded to the surface 12b of the base layer 12 not covered with the metal layers 14. The base layer 12 and the protective layer 16 contain a resin that includes an imide bond in a repeating unit.
